CAN/CSA-ISO/IEC 14776-326:04 (R2012)

This National Standard of Canada is equivalent to International Standard ISO/IEC 14776-326:2002 (first edition, 2002-08). 1 Scope This part of ISO/IEC 14776 defines a Reduced Block Command set for logical block devices. The Reduced Block Commands, along with the required SPC-2 commands and their restrictions described in this standard, fully specify the complete command set for RBC logical block devices. The purpose of this standard is to provide a command set of reduced requirements and options from SCSI Block Commands (SBC) for block devices (see ISO/IEC 14776-321). The reduced command set is intended to more closely match the functionality required for simple block logical units. The specified commands place no restrictions on device performance. The basic focus of this command set is to enable the command and control of rigid disks and removable media devices attached to Serial Bus and utilizing SCSI Serial Bus Protocol 2 (SBP-2) (ISO/IEC 14776-232).
